It is generally accepted that the physical environment in towns and cities can affect patterns of crime and antisocial behaviour. This report presents the proceedings of an international conference, held in Poland in October 2000, as part of the work programme of the Congress of Local and Regional Authorities of Europe (CLRAE) of the Council of Europe to develop and promote policies for the reduction of urban crime in its 41 member countries. The conference discussions focused on four key themes: housing and crime; open spaces, street planning and design; urban transport planning to reduce crime; and the relationship between the siting and design of sporting facilities and crime.
